Frequently Asked Questions

Q: How does the Clearwater Alpha Spherical Septic Tank work?

A: The Clearwater Alpha Spherical Septic Tank uses a three-stage process:

  • Formed from a single chamber, the sewage from a domestic property or small business premise is collected and retained in the tank.
  • Time allows it to be anaerobically digested, breaking the solids down into sludge.
  • The excess effluent liquid then flows from the tank, via the outlet, and into a suitable drainage field system for treatment.
